An arrangement for selecting sectors on a rotating magnetic storage device comprises a ring counter, each stage of which corresponds to a sector boundary, a selectable circuit element for each sector connected to a corresponding first and second AND circuit which are also connected to the stages of the ring counter corresponding to the sector boundaries, all the first AND circuits being connected to a first OR circuit, all the second AND circuits being connected to a second OR circuit, the OR circuit outputs being connected via respective AND circuits to produce output pulses at the beginning and end respectively of the selected sector. The arrangement is applied to a magnetic drum having 100 sectors, any of which may be manually selected by depressing a units key 0-9, Fig. 1, and a tens key Z<1>0-Z<1>9, thereby actuating an AND gate U00-U99 corresponding to the selected sector. Alternativelv, an individual key may be provided for each sector (Fig. 2, not shown). Each AND gate U00- U99 is connected to two further AND gates a1, a2; a3, a4; &c., the other inputs to which are from stages Z0-Z99 of a ring counter 200, these ring counter stages being actuated successively by sector boundary pulses from the drum. AND gates a1, a3 &c. are connected to an OR gate 01 whose output produces a " beginning of sector " pulse Za via an AND gate A1; and AND gates a2, a4 &c. are connected to an OR gate 02 whose output produces an " end of sector " pulse Ze via an AND gate A2. In operation, the required sector is selected by depression of a units key 0-9 and a tens key Z<1>0-Z<1>9, and a switch 307, Fig. 3 (not shown), is closed to initiate the selection operation by producing a pulse p3 which sets a flip-flop 310 to enable a gate 309 which subsequently passes a pulse p1 coinciding with the initial sector boundary Z0. A flip-flop 306 is thus set to enable AND gates A1, A2 so that when the selected sector is reached, a flip-flop 301 is switched on by the " beginning of sector " pulse Za and switched off by the " end of Sector " pulse Ze, the output of the flip-flop 301 controlling reading or writing by a transducer head 302.

Abstract: 1,238,419. Amorphous propylene copolymers. SUMITOMO CHEMICAL CO. Ltd. 18 July. 1969 [18 July, 1968 (2); 3 July, 1969], No. 36279/69. Heading C3P. Amorphous copolymers of propylene and a copolymerizable polyene hydrocarbon or halohydrocarbon are prepared by polymerization at +30‹ to -130‹ C. in the presence of a catalyst comprising a trialkyl aluminium and a vanadium halide and terpolymers of ethylene, propylene and a copolymerizable polyene hydrocarbon or halohydrocarbon, are polymerized at +30‹ to -130‹ C. in the presence of a catalyst comprising a dialkyl aluminium halide and a vanadium halide. Amorphous polymers comprising 75- 99À9 mole per cent of propylene units, 0-25 mole per cent of ethylene units and 0À1-25 mole per cent of units derived from a copolymerizable polyene hydrocarbon or halohydrocarbon and having an intrinsic viscosity of 0À5-7 dl./g. as measured in xylene solution at 70‹ C., are claimed per se. In the examples, propylene and 1,4-hexadiene are copolymerized using (ethyl) 3 A1 and VCl 4 ; proplyene and isoprene dicyclopentadiene or; 1,5-cyclooctadiene with (Ethyl) 3 Al and VCl 4 , propylene and 5- ethylidene-2-norbornene with (i-butyl) 3 Al and VCl 4 ; propylene ethylene and 5-ethylidene-2- norbornene with (etnyl) 2 AlCl. and VCl 4 , and propylene, ethylene and 1,4-hexadiene with (n-hexyl) 2 AlCl and VCl 4 , using n-heptane, hexane and tetrachloroethylene as inert solvents. Compositions of a selection of the polymers and #-phenyl-naphthylamine, stearic acid, zinc white, carbon black, sulphur, tetramethylthiuram. monosulphate, and mercaptobenzothiazole are cured.

Abstract: 1,250,996. Pyridopyrimidinones. AMCHEM PRODUCTS Inc., and MAUMEE CHEMICAL CO. 25 June, 1969 [26 June, 1968], No. 32035/69. Heading C2C. The invention comprises pyrido-[3,2-d]-pyrimidine-2,4-(lH,3H)-diones of formula in which R and R<SP>1</SP> are always dissimilar, R<SP>1</SP> is H or C 1-4  alkyl; R is C 2-8  alkyl, cycloalkyi, alkenyl or alkynyl, #-C n H 2n -, where # is unsubstituted phenyl, mono- or di-substituted phenyl bearing one or two methyl and/or methoxy and/or chlorine substituents, pyridyl or tetrahydrofuryl and n is 1 or 2, phenyl, or an N-bonded C 4-7  nitrogen containing heterocycle or dimethoxyethyl, and salts, derivatives of the ketone function and complexes thereof. They may be prepared by: (1) reacting an N<SP>2</SP> -  substituted - 2,3 - pyridinedicarboxamide with an alkali metal or alkaline earth metal hypohalite and hydroxide; (2) reacting ethyl 3- aminopicolinate with phenyl urea; (3) reacting 3-aminopicolinic acid with phenyl isocyanate, or (4) cyclizing a 1-alkyleneimino-3-(2<SP>1</SP>.carb. ethoxy-3<SP>1</SP>-pyridyl) urea. Suitable salts include acid addition salts formed with the N-atoms and salts formed with bases by the enolic form of the ketone function, derivatives of the ketone function include ketals and semicarbazones and the complexes may be formed with phenolic compounds. 2,3 - Pyridinedicarboximide is prepared by reacting the corresponding acid with acetamide and acetic anhydride and is then converted into N<SP>2</SP> - isopropyl - 2,3 - pyridinedicarboxamide by reaction with isopropylamine. Ethyl 3-aminopicolinate is prepared by esterifying the acid and is then reacted with phosgene to give ethyl 3-isocyanato-picolinate which is in turn reacted with N-aminopiperidine to give 1 -piperidino-3 - (2-carbethoxy-3-pyridyl) urea. The compounds of the invention are used as herbicides, specifically aquatic herbidices.

Abstract: 1,252,117. Cooling exothermic reactions. KRALOVOPOLSKA STROJIRNA NARODNI PODNIK. 23 April, 1970 [23 April, 1969], No. 19520/70. Heading B1X. Cooling of exothermic synthesis mixture passing down catalyst bed 6, Fig. 1, is effected by introducing cool fresh synthesis mixture at coffers 19. The cool mixture is introduced through pipes 22, Fig. 4, into the coffers 19. There is a space in the catalyst bed below each coffer 19. In use, synthesis mixture is introduced at 16, Fig. 1, and is passed for heating up heat exchange tubes 11 to electrical heater 12, whence the mixture passes down catalyst bed 6 where it is cooled by gas from coffers 19. The mixture then passes up between tubes 9 and 10 and then down between heat exchange tubes 11 and leaves at 17. The reactor may be used for methanol or ammonia synthesis e.g. from N 2 /H 2  mixture.
